Abstract

Termination tooling for use with a bench press for terminating a flat cable in an elongate connector. The tooling includes a termination die and positioning structure for holding a connector in place for termination by the die. Stop structure is disposed spaced from the termination die for engaging one end of the cable with the axial direction of the cable being generally normal to the longitudinal direction of the connector so as to locate the cable end with respect to the connector. Finally, the tooling includes slide structure for supporting the cable. The slide structure is movable transversely of the axial direction of the cable between a loading position, wherein the cable engages the stop structure, and a termination position, in which the cable is positioned for termination in the connector by the die, whereby the cable is positioned with respect to the connector without the stop structure engaging the cable during termination.

2. Termination tooling as set forth in claim 1 wherein said cover and base of said connector have respective first and second ends and further have an insertion position wherein the spacing between said elements and cover is sufficient to permit insertion of said cable therebetween, said cover and base being relatively movable to a connector termination position wherein said cover and base are closer to one another than in said insertion position and each terminal element engages its corresponding flat cable conductor, a pair of corresponding ends of said cover and base in said insertion position forming an open end of said connector to enable a cable to be inserted into said connector past said open end.

3. Termination tooling as set forth in claim 1 wherein said positioning means comprises a channel for holding a connector and guiding said connector into position for termination by said die.

4. Termination tooling as set forth in claim 3 wherein said slide means comprises alignment means for aligning and maintaining alignment of the various terminal elements of a connector with corresponding flat cable conductors upon movement of said slide means.

5. Termination tooling as set forth in claim 4 wherein said alignment means comprises a lip for engaging a side of said flat cable, and further comprising a finger extending over said channel for pushing a connector toward said die, the spacing between said lip and said finger normal to the axial direction of said cable being analogous to the spacing between an end of said connector and the terminal element closest thereto.

6. Termination tooling as set forth in claim 1 wherein said stop means is adjustable and comprises first means for locating said cable end recessed with respect to the envelope of said connector, said stop means further comprising second means for locating said cable end substantially flush with said connector envelope.

7. Tooling as set forth in claim 3 further comprising a base having side walls, said base carrying said channel intermediate and generally parallel with respect to said side walls.

8. Tooling as set forth in claim 7 wherein said base is substantially symmetrical about the longitudinal center line of said channel.

9. Tooling as set forth in claim 7 wherein said slide means comprises a generally rectangular tray, said channel being defined by a pair of intermediate walls, said tray being received between and guided by one of said side walls and the intermediate wall facing said side wall.

10. Tooling as set forth in claim 7 wherein said termination die is carried by the rod of said bench press, said tooling further comprising a back wall mounted on said base for limiting movement of said connector and said cable.

11. Tooling as set forth in claim 10 wherein said tooling includes means for mounting said back wall at spaced locations with respect to said rod whereby, depending upon the length of the connector to be terminated, the back wall can be moved to locate the connector to present an approximated balanced load to said rod.

12. Termination tooling adapted for use with a prime mover, such as a bench press, for terminating flat cable in an elongate connector, said connector comprising an insulative base and an insulative cover having a plurality of spaced insulation displacement metallic terminal elements extending toward said cover and corresponding in number and position to the conductors of said flat cable, said tooling comprising:

a termination die for terminating said cable in said connector;

positioning means for positioning a connector in position for termination by said die;

slide means for moving said cable transversely of its axial direction into position for termination; and

stop means positioned adjacent said slide means for engaging said flat cable and locating said flat cable in a predetermined position relative to said connector, said slide means being movable relative to said stop means, said stop means being spaced from said termination die whereby said flat cable can be moved into position for termination in a predetermined position relative to said connector without said stop means engaging said cable during termination.

13. Termination tooling adapted for use with a prime mover, such as a bench press, for terminating flat cable in an elongate connector, said connector comprising an insulative base and an insulative cover having a plurality of spaced insulation displacement metallic terminal elements extending toward said cover and corresponding in number and position to the conductors of said flat cable, said tooling comprising:

a termination die for terminating said cable in said connector;
